Fridge Organization

I have a single zone fridge and find drinks like to turn the fridge into a avalanche. I tries some 4 drink (can) holders from Amazon but they didn't grip the cans enough to not let them fall out when driving. Just curious if anyone has found anything that has made organizing their 12v fridge easier.

 

I use various sizes of silicone ice trays(?). They are cheap at Daiso or dollar stores. I shove them between cans and bottles to keep them from rattling while driving or off road. Works like bubble wrap, is waterproof, and can freeze but still stay flexible.
